基于STM32的指纹门禁系统的设计

Design of Fingerprint Access Control System Based on STM32

本文针对传统门禁系统中的智能化低下、控制与维修过于复杂的问题,考虑到传统门禁系统主要采用被动安防模式的欠智能化系统,除了自身机械结构和设计缺陷影响外,也很容易受到外界干扰,经常有使用失常以及识别错误的事情发生,因此对门禁的智能化研究具有现实意义。本文设计了一种采用STM32系列的微处理器作为主控芯片,用指纹识别的模式来实现门禁系统的开放与关闭,并实现了语音提示的功能的指纹门禁系统。结合设计的样品验证表明,该系统能有效地实现上述功能,解决了传统门禁系统的缺陷。

Aiming at the limited intelligentialization,difficulties of control and maintenance of traditional access con-trol system,and concerning its passive security mode which is less smart and vulnerable to design defects as well as outside influences,this paper designs a fingerprint access control system which uses STM32 series microprocessor as the main control chip and uses the fingerprint recognition mode to realize the opening and closing of the access con-trol system and realize the function of voice prompting. The verification of the designed samples shows that the sys-tem can effectively realize the above functions and solve the defects of the traditional access control system.
